Rhythm. Normal cardiac rhythm arises from the SA node (sinus rhythm) but pacemaker impulses can come from ectopic foci in the atria, the AV junction, and the ventricles under abnormal conditions. When an ectopic impulse occurs singly, it generates a beat; when the beat repeats itself, it becomes a rhythm.
The Ksp value is calculated from the concentrations of the products of Ca(OH)2 when the compound is added to an aqueous solution. Calculating the value requires knowing those concentrations, the...

Determine whether a precipitate will form if 20 ml of 1 Ã 10â7 m agno3 is mixed with 20 ml of 2 Ã 10â9 m nacl at 25 c. for agcl, ksp = 1.8 Ã 10â10 . 1. agcl precipitates. 2. agcl does not precipitate.
